I need to replace my Volvo S80 and have been looking at the new, very fuel-efficient diesel engine cars (Blue Motion, Greenline, Volvo Drive-e etc). But the problems with DPFs and dual mass flywheels are putting me off. Can you recommend a reliable car that won't involve expensive repairs later on? The range I am looking at is large family cars like the Passat, Superb etc. I would like to get a one or two year old car to avoid the large depreciation hit.
